Hands-on tutorials for Claude Code, AI agents, cloud and system design
Debug config problems in Claude Code before they cost you hours. When hooks refuse to fire, permissions seem ignored, or MCP servers stay invisible, the cause almost always traces back to a file that didn’t load, a scope you forgot about, or a variable quietly overriding everything. This guide walks you through the full diagnostic… Continue reading
Authentication is the gatekeeper for every Claude Code session. Before the CLI can answer a single prompt, it needs a verified credential that proves who you are and which plan backs your usage. This guide walks through all six authentication methods, the OAuth browser flow, cloud provider setup, token precedence, and the troubleshooting steps that… Continue reading
Best practices for Claude Code separate developers who ship clean code from those who fight the tool all day. The context window fills fast, and performance drops as it fills. These best practices help you manage context, verify work automatically, and build habits that make every session more productive. Best Practices: What You’ll Learn This… Continue reading
Output styles change how Claude Code talks to you, not what it knows. They reshape the system prompt to set the role, tone, and format of every response. This guide walks through the four built-in styles, shows you how to build a custom one, and explains when to keep coding instructions turned on. Output Styles:… Continue reading
Prompt caching is the single biggest lever for cutting Claude Code costs on long sessions. It lets the API skip reprocessing your entire conversation history on every turn, billing you roughly one tenth the normal input rate for repeated prefixes. This guide covers how the cache is organized, the eight actions that invalidate it, the… Continue reading
Code review is the part of shipping software that everyone respects and almost no one enjoys. Claude Code’s code review feature takes the repetitive burden off your team by running a fleet of specialized agents over every pull request and posting inline findings as comments on the exact lines that need attention. This guide walks… Continue reading
Common workflows are the everyday recipes that turn Claude Code from a clever chat tool into a dependable pair programmer. This guide walks through the daily-use prompts you reach for during a normal workday: understanding code, fixing bugs, refactoring, writing tests, shipping pull requests, and documenting your work. Each recipe below is ready to paste… Continue reading
Claude Code AWS Bedrock integration lets enterprises run Anthropic’s coding agent through their existing AWS account, with all traffic flowing through AWS infrastructure rather than Anthropic’s public API. The setup hinges on a single environment variable, CLAUDE_CODE_USE_BEDROCK=1, but the surrounding IAM, model-access, and regional considerations are where most teams stumble. This guide walks through a… Continue reading
Claude Code Docker deployments containerize the agent so it runs in a sandboxed, reproducible environment isolated from your host system. The pattern is popular for CI pipelines, ephemeral development containers, devcontainer setups inside VS Code, and locked-down enterprise environments where running an AI agent directly on a developer laptop is not acceptable. This guide covers… Continue reading
Claude Code for Python projects benefits more from a well-tuned CLAUDE.md than from any other configuration step. Python’s fragmented packaging landscape, its import conventions, and the gap between a Python-aware AI agent and a generic one all live or die on what you put in your project memory. This guide covers the CLAUDE.md patterns, slash… Continue reading
Claude Code for React and TypeScript projects benefits from the fact that TypeScript is the language Claude itself is built in and the one Claude Code’s training data covers most densely. But default Claude Code behavior still produces code that fights the conventions of a specific TypeScript project: the wrong import style, the wrong component… Continue reading
Claude Code vs Copilot migration is the decision an increasing number of teams are running as GitHub Copilot’s April 2026 default-data-training policy pushed developers to evaluate alternatives. The migration is not a one-for-one swap. The two tools occupy different points on the AI-assisted development spectrum, and a successful transition requires unlearning Copilot habits as much… Continue reading
Agent orchestration is the layer above subagents and agent teams: deciding which topology a task needs, what that choice costs, and which controls keep a multi-agent run honest. Claude Code gives you the primitives. It does not decide when delegation helps or when it quietly makes things worse. Agent orchestration: What You’ll Learn This guide… Continue reading
Python SDK 1.0 shipped on August 20, 2026, moving the anthropic package out of its 0.x prefix and into a stable 1.x line. This guide covers every breaking change that can touch real code, reproduces the exact errors you will hit, and walks one project through the complete upgrade from 0.125 to 1.0. Python SDK:… Continue reading
